Hi, with driver version 550.90.07 i get this:

Not sure when it broke, i'm not even sure if this is the driver's fault and has nothing to do with this software, in which case feel free to close this immediately.
Version: 0.0.12-1
OS: archlinux

If you need any other info please let me know.

It looks like you're running the 470.123.45 kernel module. That won't work with 550.90.07 userland. If you haven't rebooted yet, try that. And if that fails, try to reinstall the nvidia kernel module of the correct version.
Userland version and kernel module version should match.

Hi, thanks for helping out.
I'm pretty sure my setup is correct, and that number is coming from this #276 instead.

I also found this similar issue #211 that may be related.

I've added a fix to master to attempt to get the version number from somewhere else if it's not available through the normal mechanism. The fact the normal mechanism isn't working is a bit concerning.

Thank you.
In your opinion would detecting the right version fix this error as well?

[elFarto]

Probably.

Hello, I experienced the same issue and it's fixed in aur/libva-nvidia-driver-git which contains the new version fetcher. Can you make a new release so more people can receive the fix? Thanks.
